Hi there,

 

I have a requirement to trigger a business process with a parameter value from an anonymous web service and get errors while publishing the code in the Creatio environment. Below I have mentioned the complete code of the web service and the error screenshot of the error.

 

Note: I have pre-created the business process with the parameter and written the web service.

I referred other community articles such as 

https://community.creatio.com/articles/web-service-without-authorizatio…

https://community.creatio.com/questions/calling-business-process-parame…

These codes currently seem to be outdated and not working in the Atlas version of creatio. Please give me suggestions to resolve this issue.

 

Code :

 

/* The custom namespace. */

namespace Terrasoft.Configuration.WSO2WSConfirmationServiceNamespace

{

    using System;

    using System.ServiceModel;

    using System.ServiceModel.Web;

    using System.ServiceModel.Activation;

    using Terrasoft.Core;

    using Terrasoft.Web.Common;

    using Terrasoft.Core.Entities;

    using Terrasoft.Core.Process;

    using Terrasoft.Core.Process.Configuration;

    [ServiceContract]

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

    public class WSO2WSConfirmationService : BaseService

    {

        /* The link to the UserConnection instance required to access the database. */

        private SystemUserConnection _systemUserConnection;

        private SystemUserConnection SystemUserConnection

        {

            get

            {

                return _systemUserConnection ?? (_systemUserConnection = (SystemUserConnection)AppConnection.SystemUserConnection);

            }

        }

        /* The method that returns the confirmation of buttons. */

        [OperationContract]

        [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped,

        ResponseFormat = WebMessageFormat.Json)]

        public string ConfirmationService(string guid, bool status)

        {

            new Guid(guid);

            string result = "Guid is missing";

            if (!string.IsNullOrEmpty(guid)) {

                if (status == false)

                {

                    var manager = UserConnection.ProcessSchemaManager;

                    var processSchema = manager.GetInstanceByName("WSO2Process_3c0d24a");

                    var moduleProcess = processSchema.CreateProcess(UserConnection);

                    if (processSchema.Parameters.ExistsByName("ProcessSchemaConfirmationId"))

                    {

                        moduleProcess.SetPropertyValue("ProcessSchemaConfirmationId", guid);

                    }

                    moduleProcess.Execute(UserConnection);

                    /*ProcessSchema schema = UserConnection.ProcessSchemaManager.GetInstanceByName("WSO2Process_3c0d24a");

                    //schema = UserConnection.ProcessSchemaManager.GetInstanceByUId(leadManagementProcessUId);

                    //different engines for interpretable and compiled BP

                    bool canUseFlowEngine = ProcessSchemaManager.GetCanUseFlowEngine(UserConnection, schema);

                    if (canUseFlowEngine)

                    {

                        var flowEngine = new FlowEngine(UserConnection);

                        var param = new Dictionary();

                        param["ProcessSchemaConfirmationId"] = guid.Id.ToString();

                        flowEngine.RunProcess(schema, param);

                        

                    }

                    else

                    {

                        Process process = schema.CreateProcess(UserConnection);

                        process.SetPropertyValue("ProcessSchemaConfirmationId", guid.Id);

                        process.Execute(UserConnection);

                    }*/

                    result = "Response posting is cancelled, You can close this tab";

                }

                else {

                    result = "WSO2 endpoint intergration is pending";

                

                }

            }



            

            return result;

        }

    }

}

Found the answer for this mentioned issue, Please refer to the code below. Using IProcessExecutor, this can be simply achieved in the 8.0 version.

/* The custom namespace. */

namespace Terrasoft.Configuration.WSO2WSConfirmationServiceNamespace

{

    using System;

    using System.ServiceModel;

    using System.Collections.Generic;

    using System.ServiceModel.Web;

    using System.ServiceModel.Activation;

    using Terrasoft.Core;

    using Terrasoft.Web.Common;

    using Terrasoft.Core.Entities;

    using Terrasoft.Core.Entities.Events;

    using Terrasoft.Core.Process;

    using Terrasoft.Core.Process.Configuration;

    [ServiceContract]

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

    public class WSO2WSConfirmationService : BaseService

    {

        /* The link to the UserConnection instance required to access the database. */

        private SystemUserConnection _systemUserConnection;

        private SystemUserConnection SystemUserConnection

        {

            get

            {

                return _systemUserConnection ?? (_systemUserConnection = (SystemUserConnection)AppConnection.SystemUserConnection);

            }

        }

        /* The method that returns the confirmation of buttons. */

        [OperationContract]

        [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped,

        ResponseFormat = WebMessageFormat.Json)]

        public string ConfirmationService(string guid, bool status)

        {

            try

            {

                new Guid(guid);

                string result = "Guid is missing";

                if (!string.IsNullOrEmpty(guid))

                {

                    if (status == false)

                    {

                        {

                            // getting  IProcessExecutor

                            IProcessExecutor processExecutor = SystemUserConnection.ProcessEngine.ProcessExecutor;

                            // List of input parameters

                            var inputParameters = new Dictionary<string, string>

                            {

                                ["ConfirmationId"] = guid.ToString(),

                            };

                            //code of the process

                            string processSchemaName = "WSO2Process_3c0d24aCustom1";

                            //execute the process

                            ProcessDescriptor processDescriptor = processExecutor.Execute(processSchemaName, inputParameters);

                            //return processDescriptor;

                        }

                        

                        result = "Response posting is cancelled, You can close this tab";

                    }

                    else

                    {

                        result = "WSO2 endpoint intergration is pending";

                    }

                }

                return result;

            }

            catch (Exception ex)

            {

                return "GUID error - " + ex.Message; 

            }

            

        }

    }

}
